CIS Discovery Exam Preparation Questions with Certified Solutions

CIS Discovery Exam Preparation Questions with Certified Solutions What is the purpose of the CMDB? To capture and catalog business assets, provide a clear picture of service management, better provide support. What is a CI? An infrastructure component (hardware or software) required to deliver a service. What are the key tables in the CMDB? Configuration [cmdb_ci], CI Relationship [cmdb_rel_ci]. What is the logical model to show how CI's are related? Dependency View. What classes extend from [cmdb_ci]? Hardware [cmdb_ci_hardware], Application [cmdb_ci_appl]. What are the parent and grandparent classes of the Server class [cmdb_ci_server]? Parent is Computer [cmdb_ci_computer], Grandparent is Hardware [cmdb_ci_hardware]. What are the parent and grandparent classes of the Tomcat server class [cmdb_ci_app_server_tomcat]? Parent is Application server [cmdb_ci_app_server], Grandparent is Application [cmdb_ci_appl]. Changes to to attributes in Hardware table will affect software (application) table structures (true/false)? False. Only attributes in child (extending) classes will be changed (e.g. changes to attributes in hardware table will propagate down to server table, as this is an extending table). How do you navigate to see the hierarchy for a particular CI type? Configuration > CI Class Manager, locate CI type in Class Hierarchy, use its Show Schema Map related link. How does the CMDB support Incident Management? Ability to identify how faulty CI's affect upstream services means being able to warn users of potential outages, or reassure customers that work is currently in progress. Relating component information to quick fixes can affect faster workarounds. How does the CMDB support Problem Management? Able to perform root cause analysis on related items, narrowing down the source of incidents and identify the faulty CI more quickly. How does the CMDB support Change Management? Understand change impact for more informed decision-making, identify upstream services and CI's affected by a change so change schedules can minimize service disruption. How does the CMDB support Security Management Identify assets and their business value to ascertain monitoring and control requirements. The CMDB provides increased visibility of the infrastructure. What does this enable? It enables key decision-makers to quickly make accurate and informed decisions, and for support teams to to investigate and resolve issues in a timely manner. What risks are introduced by support staff not fully understanding their environment? Support staff are not informed when devices are moved , Technicians lack details of a new server added to the network, Software is installed on corporate equipment without proper official approval, Costs and fines associated with under or over-buying software licenses. How does a poorly maintained CMDB impede service management processes? Incident resolution times extended due to additional information-gathering stages, prolonging outages. Problem investigators searching in the wrong place or overlooking related items due to lack of configuration data. Misunderstood change impact (unclear dependencies) could result in major incidents or catastrophic service outages. What is ServiceNow Discovery? It interrogates the enterprise recognizable devices and applications they host. Delegates work to MID servers. Define the MID Server. What is its purpose? MID: Management, Instrumentation and Discovery. It is a lightweight Java process running under a Linux or Windows platform that resides within enterprise networks. Function: to execute work requests and return results to a SN
